[light jay]

it is

its Player Input Manager

[hard viper]

how does OverlapCollider work with DefaultContactOffset?

[hexed pecan]

Are you asking if defaultContactOffset affects OverlapCollider?

[hard viper]

yes

basically, if my shapes have a distance between 0 and DefaultContactOffset, does that count as overlap?

and to .Distance() ?

I assume Distance does not care about DefaultContactOffset

[hexed pecan]

Good question 🤷‍♂️ maybe test it out?

I can't even guess if it affects physics queries or just actual collisions

[lean sail]

do you have multiple instances of PlayerInputManager and can you show the inspector tab for that game object?

[hard viper]

ok, it does

[wanton wasp]

I have a weird problem with enemy spawning.
It works just fine in the editor and windows build but doesn't in android build.
Also, sometimes it spawns some of them right.

It always report the same spawn position on both windows and android.

[hard viper]

OverlapCollider does give everything that DefaultContact offset.

I really wish the documentation specified that, or at least allowed that to be a parameter

omg AND Distance() is ALSO modified by it!

all these casting methods do this!

If I cast Col1 with col2 behind it, with a distance < 2 * DefaultContactOffset, it registers the hit with zero distance

and the distance is so strange

With DefaultContactOffset = 0.1, cast col1 into col2, where actual distance = 0.2 (2x offset), then it registers a raycasthit with = 0.015

the exact distance for distance = 0 is 0.185. Q: What and why lmao

I don't understand why it's not even 2x DefaultContactOffset

ok, so the last question I think I need answered is why Cast gives a RayCastHit with distance that is not exactly off by 2x DefaultContactOffset. like, where is that 0.015 comming from?

in the purest sense, a FSM is basically an enum, and whatever you do to change it

[ebon sluice]

how would i go about rotating a ui object towards the mouse position? the code for rotating a gameobject towards the mouse doesnt apply for ui objects, and i cant seem to find anything about it

[hexed pecan]

Pretty sure you can just change the recttransform's Z angle to face towards Input.mousePosition

Setting transform.up to the direction towards the mouse should work too

[ebon sluice]

nah because its a UI object and input.mouseposition would get the mouse in world space not ui space

[hexed pecan]

Yeah you gotta do some conversions

[ebon sluice]

is there not a variable for mouse position in ui space?

[hexed pecan]

Not that I know of

[lean sail]

https://docs.unity3d.com/ScriptReference/Input-mousePosition.html
it is in pixel coords

[hexed pecan]

Pretty sure you have to use https://docs.unity3d.com/ScriptReference/RectTransformUtility.html for the screenspace -> UI space conversion or vice versa

This?

At least according to an answer here https://forum.unity.com/threads/get-real-screen-position-for-a-canvas-ui-element.449455/#:~:text=897-,Can't you use%3B https%3A//docs.unity3d.com/ScriptReference/RectTransformUtility.html to do the conversions%3F,-Android games%3A

did it

[jaunty plume]

i cant find anything i can understandabout the purpose of W from quaternion
if i do stuff to W from quaternion, it completly gets bugged

couldnt understand neither from videos, neither from articles

[hard viper]

this makes no sense to me

[jaunty plume]

same

[lean sail]

you shouldnt be manually modifying the components of a quaternion, what is this for?

[hard viper]

if DefaultContactOffset = 0.001, then casts can only generate RayCastHit2D where distance = 0 from shapes overlapping

[jaunty plume]

if i change any of the W from quaternion to always 0, it completly bugs

                    SmoothCameraValues = Quaternion.SlerpUnclamped(Quaternion.Euler(Camera.main.transform.eulerAngles.x, Camera.main.transform.eulerAngles.y,0), Quaternion.Euler(MouseLookEuler.x, MouseLookEuler.y, MouseLookEuler.z), CameraDelay*Time.deltaTime);
                    Camera.main.transform.rotation = new Quaternion(SmoothCameraValues.x, 0, SmoothCameraValues.z, SmoothCameraValues.w);
                    transform.rotation = new Quaternion(0, SmoothCameraValues.y, 0, SmoothCameraValues.w);

also somehow the Y from transform.rotation doesnt work

[jaunty plume]

but more about that a bit later

[lean sail]

quaternion values are not the same as euler, what you wrote wont work at all

[quartz folio]

What you're doing is nonsensical. Don't directly modify values from a quaternion, or build your own

[hard viper]

when working with quaternions, you don't want to manually set coordinates unless you know what you are doing. and you don't know what you are doing

[jaunty plume]

so just keep it the same?

[quartz folio]

https://unity.huh.how/programming/quaternions/members

[hard viper]

you want to make quaternions via constructors (like Quaternion.Identity, or Quaternion.Euler etc). Then operate on them

[jaunty plume]

what do you mean by that?

[hard viper]

you make a quaternion using something like Quaternion.Euler(0,0,-270f)

that is a quaternion that corresponds to a rotation for a specific Euler angle

[jaunty plume]

i know that

[hard viper]

ok, then you can do things like quaternion1 * quaternion 2

you should not go in and try to change the guts of a quaternion

Quaternion.RotateTowards is also useful

https://docs.unity3d.com/ScriptReference/Quaternion.html

Quaternion has a bunch of methods to modify quaternions

[lean sail]

also please cache some of those values, those lines you wrote are incredibly long. the commented one doesnt fit in your screenshot even

[hard viper]

myQuaternion = new Quaternion(calculatedX, calculatedY, calculatedZ, calculatedW) is definitely NOT a constructor you should use unless you deeply understand quaternions

do you understand?

[jaunty plume]

the commented one is older attempt which i didnt deleted yet

[jaunty plume]

this one yes

[lean sail]

still, you would improve readability by quite a bit by even just caching the camera.main.transform at the beginning of that if statement

[hard viper]

you can just drop newlines in the middle of a long line

that's all one line

[lean sail]

please my eyes

[jaunty plume]

i have a weird habit of writting a very long line

[lean sail]

if i saw this in a code review, you're getting a talking to

[hard viper]

I fixed the indent 🙂

[jaunty plume]

i made this in another programming language and it's all in one line
VForce = vec(SpeedVector:x() * cos(Duplicated:angles():yaw())*cos(Duplicated:angles():pitch()) - SpeedVector:y() * sin(Duplicated:angles():yaw())*cos(Duplicated:angles():pitch()) + SpeedVector:z() * sin(Duplicated:angles():pitch()),SpeedVector:x() * sin(Duplicated:angles():yaw()) * cos(Duplicated:angles():pitch()) + SpeedVector:y() * cos(Duplicated:angles():yaw()) * cos(Duplicated:angles():pitch()) - SpeedVector:z() * sin(Duplicated:angles():yaw()) * sin(Duplicated:angles():pitch()), SpeedVector:x() * sin(Duplicated:angles():pitch()) * sin(Duplicated:angles():yaw()) - SpeedVector:y() * cos(Duplicated:angles():pitch()) * sin(Duplicated:angles():yaw()) + SpeedVector:z() * cos(Duplicated:angles():yaw()))

[hard viper]

ok that's not a good use of this knowledge

[jaunty plume]

like this is the comparison of length

[jaunty plume]

i put the kind of lua code into c# file that's why some parts are red

[lean sail]

I dont know if you're proud of that, but you really shouldnt be. This kind of style is completely unreadable to anyone who has to work with you or is trying to help

[jaunty plume]

i know, someone said hyperobfuscator 3000 XD

[hybrid turtle]

hye guys how do you disable the same button from being clicked more than once?

[leaden ice]

when you say "button" what do you mean exactly?

[hybrid turtle]

like I actually mean an object with button component attached to it

also i figured out the git

lmao he had lfs enabled

[leaden ice]

disable the button in the first click

or set to interactable = false

[hybrid turtle]

ok after the click set intercatable to false

but then after they click on another button and come back

[leaden ice]

yea

[hybrid turtle]

need a way to set interactable = true

[leaden ice]

reactivate it at that point

[hybrid turtle]

            interactButton.onClick.AddListener(delegate {
                foundObject.animationPlayEvent(); 

            }); ```

my predicament is that each of my buttons use this same script

[elfin tree]

hey so i made a save system using unity serializables, thing is, it seems to store and instance id, even though they should be serializable, what am I missing?

[leaden ice]

this means you're trying to serialize a MonoBehaviour directly

you can't do that

[elfin tree]

and would it be fine to serialize a serializable scriptable object?

[leaden ice]

I'm not sure - pretty sure that has the same problem too

You should make a class specifically for holding serializable data

[elfin tree]

hmmm.. and is it possible to serialize a reference to a scriptable object then?

not the whole object

[leaden ice]

Sure, using Addressables, or using the path for Resources.Load

[elfin tree]

okay, will look into it

thanks

[elfin tree]

and i assume that's still more costly than storing a custom uuid i made, and then getting the element with the same uuid from a list? if you understand what i mean

[hybrid turtle]

ok so I have no clue where and when to reactivate it cuz my problem ssems a bit tricky

two different instances of the same event listener used for the two buttons

and need a way so the last button is not hit

[ember hinge]

Any idea on what i can do? i have an object pool system for shooting, bullet tracers, hit impacts, blood etc, this is only one shot which penetrated 2 walls so 4 impact fx, the ms is almost over 0.3-0.4. i really dont know what to do. If i keep all of them active itll be an insane amount of objects active and if i keep deactivating and activating it hurts performance.

[leaden ice]

how many GameObjects are in this impact prefab?

maybe you can reduce its complexity

[ember hinge]

3, a vfx, and a shader decal we made since decals are expensive

[leaden ice]

Does it help at all if you just throw all the components on a single object?

Also what does the PlayRandomSound code look like? Seems a little slow

[ember hinge]

Hmm, I could try that Actually

[ember hinge]

private void OnEnable()
{
audioSource.clip = AudioClipExtensions.GetRandomSoundFromArray(audioClips);
audioSource.Play();
}

[hybrid turtle]

@leaden ice looks like you answered my question on unity forums

is there a solution though that doesn't involve forcing it to wait ad just nit being abke to ckucj

click

[leaden ice]

I don't understand what the issue is? set interactable to false when you click

set it back to true whenever whatever happens that should re-enable it

[hybrid turtle]

yes but then when you click on another button and come back

like its just two instances of the same handler

[leaden ice]

and AudioClipExtensions.GetRandomSoundFromArray?

[hybrid turtle]

            interactButton.onClick.AddListener(delegate {
                foundObject.animationPlayEvent(); 
            });
           ```

both buttons have this attached to it

[leaden ice]

the buttons will need to reference each other so they can re-enable each other

[hybrid turtle]

now how can I prevent double clicking but then when you click on the other and come back be able to click again

[leaden ice]

or there needs to be a central handler that references them both

and re-enables all but the clicked one

[hybrid turtle]

ok

that makes sense so a spearate script for each button?

[ember hinge]

public static AudioClip GetRandomSoundFromArray(AudioClip[] audioClipArray)
{
if (audioClipArray.Length > 0)
{
return audioClipArray[Random.Range(0, audioClipArray.Length)];
}
return null;
}

[hexed pecan]

It might just be that it takes some time to load the audio clip

This could help a bit https://docs.unity3d.com/ScriptReference/AudioClip-preloadAudioData.html

But yeah seems like thats not the main thing affecting performance there

[ember hinge]

Yea, it’s mainly the .setactives. But maybe packing it on one gameobject like he said and no child’s would help

[hexed pecan]

Yeah that will probably help

I tend to not abuse extra gameobjects for this reason

[floral geyser]

Okay I'm trying to use Splines, and it seems like there's not a whole lot of built-in functionality; I'm trying to get the evaluation position of a BezierKnot on a Spline, and I'm not sure how to do that. I'm a little surprised the BezierKnot doesn't already have that info within it

For instance, a BezierKnot exactly halfway through the spline would be at position 0.5 on the spline

[dusky lake]

Theres a few good spline tools on github, give it a quick search and save yourself some headache

[floral geyser]

Any recommendations?

[dusky lake]

ill check if i can find what i worked with last year

I tested a few, not sure which one i settled with and dont have access to the source anymore as i dont work at that company anymore

https://github.com/yasirkula/UnityBezierSolution i think i used this
https://github.com/methusalah/SplineMesh if you need meshes

[floral geyser]

Phenomenal, thanks a ton!

[dusky lake]

what is AbstractState?

No the class, is it inheriting from MonoBehaviour?

[cosmic rain]

No one would be able to help you without reading through that asset documentation. And you can't expect people to spend time on that.

To answer your question, you're expecting the animator in a constructor, but it seems like they're using some sort of factory pattern to create the states.

Anyways, the first thing to check is wether you're getting any compile errors.

[swift falcon]

can anybody suggest me a good C# and Unity tutorials to get more coding knowledge? I wanna know more lol

[fervent furnace]

What is “know more”…

[swift falcon]

well

idk

maybe there’s more i can learn

maybe there’s advanced c# unity tutorials idk about

idk how to explain😭😭😭🗿

[cosmic rain]

There's always more you can learn. But there's so much of it, you should at least have some idea about what you want to learn.

Otherwise, just open the unity/C# manual and select a random topic that you don't know about.

[jaunty plume]

Code link: https://pastebin.com/fNUXPq6n
Explaination: There is no way camera can change Y because it's set to 0 all the time, but it sets to opposite of it's parent, WHY

[swift falcon]

this is actually a pretty good idea

[jaunty plume]

guys help

[somber tapir]

is the camera attached to the player?

[somber tapir]

the rotation you see in the inspector is the local rotation, when you set the cameras world y-rotation to 0 but the parent is at -64 then it will show 64 in the inspector. You might want to use transform.localEulerAngles

[jaunty plume]

ok, let me try

it worked

[static bramble]

if i have a blender object, how do i import it into unity in a way to add a script to a specific part of it

[knotty sun]

https://docs.unity3d.com/560/Documentation/Manual/HOWTO-ImportObjectBlender.html

[glossy granite]

Hi, Im having a script that is not included in the solution by vs code for some reason, do you know any fix?

[mellow sigil]

What exactly is the problem/symptoms? Why is MonoBehaviour highlighted, is that what's not included?

[glossy granite]

sorry, I this script is not recognized by other scripts in vs code

it says type or namespace not found , and monobehaviour is not green

it is usually green when the script is being able to be found by other scripts

with intellisense in vs code

this is what I get in other scripts

but namespaces are fine both scripts have the same

cant regenerate project file since that option is missing in the last unity version god knows why

[somber nacelle]

is it perhaps in a different assembly?

[glossy granite]

that maybe the issue

how can I check that?

this happend when pulling the repo from a different computer

[somber nacelle]

are you using assembly definitions? is it in one of unity's special folders?

[glossy granite]

I didnt mean to use them

how do I find them?

[somber nacelle]

they would be the asmdef files in your project

[somber nacelle]

you would have to have deliberately created them. or you've added this file to an asset's folder that uses an asmdef

of course, it's entirely possible that isn't the issue. but you aren't really showing the proper context

[glossy granite]

i didnt deliberately created them

[somber nacelle]

just showing that you aren't getting the desired syntax highlighting doesn't really show anything. nor does a screenshot of a compile error in another script

[glossy granite]

when I click go to symbol, this script wont appear on the box, but any other one will appear

[somber nacelle]

okay so where is it

[glossy granite]

in the asset folder like every other script

[somber nacelle]

show it

[glossy granite]

unity doesnt seem to identify the error , is vs code the one that doesnt recognise the script and throw that error of type or namespace not found

[somber nacelle]

if the error only appears in vs code and you have in fact saved so that unity would compile it. then it's an issue with vs code. try reconfiguring it or use a real IDE

[glossy granite]

I remember years ago having this similar issue on windows with visual studio once, Im on linux now

[heady iris]

I use scriptable objects in many places in my game. I'm using Json.NET for serialization. I gave them unique IDs and made a converter that serializes them as their ID

then I use Resources to load all assets of a certain type of scriptable object and build an ID-to-object dictionary

which I use to turn the IDs back into objects

It's actually really convenient -- I don't have to manually do that lookup. I just defined the deserialization process to be to read the ID, grab the dictionary of the relevant type, and get the object from the dictionary

so my settings file looks like this

    "toggleSettingValues": [
        {
            "setting": "2287B3F2A40C8403FB55C03E76C90096",
            "value": true
        }
    ]

I should base64 the UUID value instead of just writing out a hex string

33% less space!

or maybe just use a binary format

[glossy granite]

solved the issue just had to add this line to assembly c sharp .csproj file

[clever trellis]

I tried the google cardboard hello app scene in unity, then exported it to android, it works as intended, but not shure why gear icon and cross button not working?

[somber nacelle]

This kind of stuff should be handled automatically by your configured tools

[glossy granite]

it usually does but maybe it had an issue for some reason

[clever trellis]

But in script there is functionality for both

[forest rivet]

why are my script variables persisting after stopping/starting the game?

like if i do something like the code below w/e the value is when I stop and then start the game it increments from that value 🤷‍♂️

health;

Update() {
health++
Debug.Log(health)
}

[dusky lake]

Did you turn off domain reload?

[forest rivet]

no

[somber nacelle]

which is why i suggested you go through the configuration process again. the fact that you also don't have the regenerate project files button indicates that you probably need to configure it again, because it has not been removed. it just does not appear if unity is not configured to use one of its supported code editors

[dusky lake]

Can you show the full script instead of pseudo code?

[hard viper]

in 2D, if I use Cast/BoxCast/Distance/etc, then the distance between polygon-based colliders (in the RaycastHit) is actualDistance - 2 * defaultContactOffset + 0.015

Question: Where does that 0.015 come from?

[ashen yoke]

bounds "shell"

probably

bounds are not precise and stick out of whatever they encompass

[hard viper]

something like that makes sense, but I need to know exactly where this comes from. The number is not random error: very reliably 0.01498-0.01499

[ashen yoke]

is that physx?

you can read its docs to find out exactly what causes it

oh its 2d, read box2d docs

https://forum.unity.com/threads/2d-raycasthit-distance-is-wrong.1171634/

post the code where you try to change position

[placid obsidian]

Heya guys,

I'm having some troubles with colliders, namely stuff getting stuck in each other.

The big cat on spawn has an animation transforming the scale be large, however sometimes stuff gets stuck inside of it. I've tried continuous/discrete collision, and never sleep for sleeping mode. I'd like for it just to push everything out of the way, but its not working. Any ideas on what I could do?

[hard viper]

thanks. this helps.

it’s probably worth asking my ultimate question here, which is; If I cast/.Distance between colliders A and B, and get back distance X (from the output), how much does A need to be moved to be in consistent contact with B?

[ashen yoke]

https://forum.unity.com/threads/physics-computepenetration-2d.1112887/

[hard viper]

eg, if I cast red block to blue block, or use.Distance to get red block out of blue block. These methods tell me distance X. How far to translate red block for consistent results

[ashen yoke]

for 3d is ComputePenetration

according to that thread the distance method does that

[hard viper]

that’s also what I’ve been using. but it also has that 0.015 offset from box2D

[ashen yoke]

if its inherent to box2d you can only work around it

all of apis will be using it, most likely

[hard viper]

I’m fine with that. I just need to know how much I need to move everything so collisions are generated properly with tolerances

[ashen yoke]

i would just eyeball it

setup complex stress test scenario, expose the offset, tweak it until the sim is stable

[hard viper]

since I’m now trying to take manual control with kinematic RBs instead of dynamic RBs, which will automatically eject themselves

it might be a good time to mention that I’m making a pseudo physics engine

maybe I should just put parameters and tweak them…

[ashen yoke]

that will give you insight

[hard viper]

MelvMay gave me insight

cast/distance all give distance until it registers contact.

linecast/raycast do not factor in defaultContactOffset (eg polygon radius) at all, and just gives the very exact value. Not necessarily where it makes contact via physics system’s metrics

[hard viper]

ok, I have… another very related question now

If I want to collide and slide, how do I do this with Cast to end in good contact?

If I cast in 1, then move to contact, I get to 2 with that slide vector, which I use for my next cast.

but I’m already in contact with slope, so woulding casting in 2 not tell me I hit the wall?

[hexed pecan]

I guess you could Vector3.Project the direction to the hit surface normal to get the direction of that bottom blue line

This is pretty complex stuff though

[hard viper]

i can do the math. that’s not the issue

[hexed pecan]

And then cast again along that line

[hard viper]

i just need to be able to do that iterative second step to end in contact with wall in 3

i guess my question is: If I move to be in contact with slope, then Cast would not see the wall, just the slope, right?

the second cast

[hexed pecan]

What do you mean with 'see the wall'?

[hard viper]

red box needs to know it is stopping at the wall

so casting at 1, I get hit on slope, move to slope

[ashen yoke]

you will be creating your own cast with discrete iterations

[hard viper]

then cast from 2, in direction along slope (toward wall), but since i’m touching slope, cast will say I’m touching it at slope, right?

[hard viper]

basically. using .Cast

[hexed pecan]

You can add a very small offset to mitigate that

Also if a collider overlaps another collider at the start of the cast, it wont detect it

[hard viper]

i guess I should give a small offset, then on the final step, move by that offset, right?

[hard viper]

that’s not my experience

and is obnoxious af

i’m pretty sure cast includes anything we’re overlapping at start

as per docs and experience

[hexed pecan]

I mean after you hit the slope, for the next cast add an offset to the origin. Something like the slope's normal * 0.0001

[hexed pecan]

Ah is it 2D?

[hard viper]

yes

so much much easier

and rotations all locked. because fuck that

i do not want to deal with torque and rotations etc, so this should be a pretty pureified easy case of this problem

[hexed pecan]

Ok, well, I proposed my solution

[hard viper]

ok so we give some offset in between iterations, then if we are done, we translate by that final small offset to be in intimate contact, right?

[hexed pecan]

The offset is just to avoid instantly hitting a collider again when you cast again

But hmm yeah you could revert the offset after all the casts are done so you get more precision 🤔

[hard viper]

hmm, right if I end at wall, I still need intimate contact with slope below…

maybe each iteration adds in the offset/skin from the previous iteration back in

0 => 1 move by x1 - f * x1
1=> 2 move by x2 + f * x1 - f * x2;
…
at end, move by f * xn

f being the offset, but being fixed magnitude

does that make sense?

[hexed pecan]

I guess yeah, if I read that correctly. I'm not a big maths guy, I understand written code better

[hexed pecan]

Is f here the scalar for the offset?

[rigid island]

not a code question

[hybrid turtle]

sorry ill redirect question to another chat

[rigid island]

try #🔀┃art-asset-workflow or #💻┃unity-talk

[hybrid turtle]

thank you @rigid island

[tribal gust]

I keep getting this every 5 seconds for like 10 times.
Why is that happening?

And how do I fix this?

This has been happening since i updated the unity hub

[heady iris]

please send screenshots, not screen photos

looks like you have a ~lot~ of console emssages

and it's stuck in ConsoleWindow.Repaint

perhaps you just need to stop logging so much

[tribal gust]

My laptop hanged because of that small white window sorry

I'll try commenting out all the log statements

Thanks

[heady iris]

You could also turn on Collapse

That would stack identical log entries together

If you want to show some information that changes every frame for debug purposes, consider using OnGUI

[tribal gust]

Does that display on the info on the game view window?

[heady iris]

Yeah, it lets you draw stuff like text and sliders on the screen

It's called "immediate mode" GUI because you run code to define what shows up every frame

[tribal gust]

Oh I needed that info.. 🥲 i was thinking to do that for so long but I just... Didn't

.

[heady iris]

    void OnGUI()
    {
        if (!debugShown)
            return;

        if (GUILayout.Button("Serialize"))
        {
            Debug.Log(SaveLoad.Serialize(progression));
        }
        if (GUILayout.Button("Test Round Trip"))
        {
            var dataString = SaveLoad.Serialize(progression);
            progression = SaveLoad.Deserialize(dataString);
        }
    }

here's a snippet from my game

It's good for making little debug interfaces

[tribal gust]

That's cool, thanks a lot!!!

[heady iris]

GUILayout automatically arranges the elements for you; GUI has you manually position them

[tribal gust]

I was logging the speed of my car in the consol btw xD

[heady iris]

np (:

If you have many vehicles you want to show all at once, you could do something like this

[tribal gust]

Yea I have like 16 learning through reinforcement learning for like 8 hours 💀

[heady iris]

void OnGUI() {
  using (var layout = new GUILayout.AreaScope(new Rect(10 + 100 * index, 10, 100, 300)))
  {
     GUILayout.Label("Speed: " + myspeed);
  }
}

that'll place car 0 at 10,10; car 1 goes at 110,etc; etc.

I often build a single "debug controller" that everyone registers themselves with

so that it can draw one big horizontal scope and then put each debuggable thing in its own vertical scope, or whatever

[warm kraken]

hey guys i have a question

[tribal gust]

Thanks a lot mate! Really helpful

[warm kraken]

is there a way to reveal and hide public variables by checking or unchecking a box in my own custom script?

how can i implement that?

[heady iris]

You can make pretty complex interfaces (with sufficient blood sweat and tears , at least)

[heady iris]

You would need to make a custom editor.

Actually -- something like NaughtyAttributes can probably help here

It's an add-on that adds useful attributes for your monobehaviours

I know that one is used to hide a field if a condition is false

Sounds like what you need.

[warm kraken]

oh great

[hexed pecan]

Yep, naughty has HideIf/ShowIf

[heady iris]

I am deeply inspired by Brigador's debug menu

iirc they use DearIMGUI

it's a beaut

debugging your game can be a drag, so you might as well make it look and feel good, hah

this is also why i've spent a few hours making custom editor icons

[hexed pecan]

I like IMGUI, no matter what the UIToolkit purists say

[heady iris]

i am tired of everything being one of these two icons

[hexed pecan]

I kinda wanna start learning cpp and make an app with dear imgui

Think theres a unity port for it but i dont see the point

[mossy jewel]

Are there any ways of allowing an object like a plane to yaw, roll and pitch using the direction of the mouse? I've used many techniques that although work with tilting, don't work with roll, so is there an easier way to do this?

[hexed pecan]

Usually when this kinda question is asked, I see the term 'PID-controller' thrown around

It's a robotics thing but applies to games too from what I understand

[leaden ice]

yaw, roll, AND pitch with just a mouse input is a tall order.
you have to bake a ton of assumptions into it.
Anything is possible of course.

[hard viper]

yes. I worked out the math. i think your suggestion of using a normal (instead of going backwards along the direction of the cast) is better

[hexed pecan]

Nice. Yeah I remember coming to that conclusion myself too

[mossy jewel]

What is a PID controller?

[leaden ice]

long story short - it's how cruise control maintains a desired speed in a car, for example

through a bunch of feedback loops and inputs into the workings of the car.

[mossy jewel]

So basically having a control that is able to only move up to a certain point unless a function or if statement is met.

[leaden ice]

inputs:

• current speed
• mass of the car
• engine telemetry (RPM, current gear, etc)
  outputs:
• gas application
• brake application

no it's a very active feedback loop of the car constantly reading its own speed and applying control inputs to achieve a specific desired outcome

https://en.wikipedia.org/wiki/Proportional–integral–derivative_controller

[mossy jewel]

Makes sense. But wouldn't this be computer power intensive?

[leaden ice]

it's not so bad

cars can do it

anyway this same principle is applied all over robotics, manufacturing, etc

anyway a PID controller would be the "how" of if you have a desired pitch/yaw/roll and want to get there in a physically realistic way, applying airplane controls (throttle, flaps, aelerons, etc)

it's not directly related to the "how to control a plane with a mouse" question

indirectly though it may be involved if you want physical realism

[mossy jewel]

True.

[hard viper]

PID effectively means you use information from past present and future

[tall salmon]

hiii!

[mossy jewel]

Alright

[hard viper]

P = present, current value.
I = integral, sum of old values
D = derivative, where it plans to go next

[tall salmon]

i dont know if there is any way to make a yield that waits until a bool is either true or false, does anyone know if there is any way?

[leaden ice]

what is WaitUnit?

[mossy jewel]

It makes a lot more sense now, i'll try to make a PID-like system for this thanks.

[tall salmon]

oh

[hard viper]

PID controllers work to try to drive a number somewhere to maintain setpoint, and sometimes, one fraction of it is left out

[tall salmon]

i readed wait until

BHAHAHAHAH

[hard viper]

many PID controllers use no integral, for example. or no derivative

[tall salmon]

let me change that rq and see if it works

[leaden ice]

you want:

yield return new WaitUntil(() => !onPurpleWall);```
or:

```cs
yield return new WaitWhile(() => onPurpleWall);```

[hard viper]

or put very little weight

[heady iris]

the present control directly adjusts the control based on the current value
the integral control uses a sliding window to add some extra input
the differential control looks at how fast the value is changing

so if the house is cold, you turn on the heat; if the house stays cold, you turn on more heat

[tall salmon]

and why are the breaks so strange?

[heady iris]

and if it catches on fire you stop, i guess

[tall salmon]

like (() )

[hard viper]

lol

[leaden ice]

wdym by "breaks"?

[leaden ice]

it's a lambda

[tall salmon]

no idea what that is

[heady iris]

(foo, bar, baz) => 3

It is a function with no name.

[leaden ice]

() => onPurpleWall is a lambda function. It takes in 0 parameters and returns the current value of onPurpleWall.
A lmabda is just a convenient inline way to define a function that doesn't have a name

[heady iris]

(x,y) => x + y is a method that takes two arguments and adds them

(and returns the result)

[leaden ice]

you could also do this:

void OppositeCurrentWallValue() {
  return !onPurpleWall;
}

yield return new WaitUntil(OppositeCurrentWallValue);
``` but that would be more verbose

[tall salmon]

deam i suck at understanding words

[leaden ice]

Basically it's just a function without a name, that's all.

https://en.wikipedia.org/wiki/Anonymous_function

[tall salmon]

do you want more context to see if i can somehow explain what i mean with the on purple wall

[heady iris]

new WaitUntil(() => Time.time > 10);
new WaitUntil(Condition);

where...

bool Condition() {
  return Time.time > 10;
}

[tall salmon]

a function is a variable?

[heady iris]

these express the same idea

[leaden ice]

functions can be stored in variables but that's not directly related to the lambda thing

it's definitely related though

in that you can store a lambda in a variable

(you can also store "normal" functions in variables)

a function stored in a variable in C# is called a delegate

[tall salmon]

a function is this?

[heady iris]

This defines a function named firstcheckpoint

Since you defined it inside a class and it is not static, I would call it an instance method.

[tall salmon]

dont clearly understand how it works

my english isnt the best

srry

[heady iris]

There are a lot of terms, yeah.

You do not need to know them all.

[tall salmon]

okay i will try to give you context

is there any page i can copy paste my code for you to revise?

since discord wont take it cuz its too large

what im trying to do is a mechanic where if you touch a purple square game object with a collider that is on layer 8, your gravity scales get reduced to 0 until you leave the wall with a dash

[hexed pecan]

Kinda sounds like you want OnTriggerEnter and OnTriggerExit?

[tall salmon]

yep

[hexed pecan]

The purple square (wall?) would have the trigger collider

[tall salmon]

but since i want to store the gravity scale wouldnt it be better to do it in an IEnumerator?

also i think it would be a OnCollisionEnter and OncollisionExit

since its a tangible wall

[tawny mountain]

How can I get on trigger enter to work for child objects that's tagged? One tagged Enemy and one tagged Head. Both child objects have colliders with is trigger and rigidbodies.

Does their parent have a rigidbody?

We discussed this here or in code-beginner a moment ago

[tawny mountain]

No , and no collider on parent

[tall salmon]

https://hastebin.com/share/lafupaxaza.csharp

[hexed pecan]

Okay, so what isn't working with your current setup?

[tall salmon]

thats the code

[tawny mountain]

I'm not getting the trigger code to execute one sec I'll provide connect

Context

[tall salmon]

it includes movement and dash and now i want to make the player stick to the wall ( i thought of removing the gravity scale for this) and since it refreshes your dash, whenever you dash out of it to just give you back the old gravity scale. idk if this idea could work or if its just inefficient and theres a better way

[hexed pecan]

Put a log in the start of OnTriggerEnter to see if it gets called at all

It could get called but your if-checks fail

[tawny mountain]

the Enemy and Head isn't working , Enemy will if i put the collider on the parent even without a rigidbody , but when I do the tags on the child objects it stops working

[hexed pecan]

Also - at least use else if so you don't do redundant checks

Like if the tag was "Enemy", why check if it was "Head" after that

[hexed pecan]

Where is the script tho?

[tawny mountain]

yeah I will be changing to this when I get it working

private void OnTriggerEnter(Collider other)
{
    if (damageEnemy)
    {
        if (other.CompareTag("Enemy") || other.CompareTag("Head"))
        {
            SkeletonHealthController enemyHealthController = other.GetComponent<SkeletonHealthController>();
            if (enemyHealthController != null)
            {
                float damage = (other.CompareTag("Head")) ? RandomDamage() * 2 : RandomDamage();
                enemyHealthController.DamageEnemy(damage);
                Logger.Instance.LogWarning($"Hit {other.name}" + (other.CompareTag("Head") ? "'s Head" : ""));
                Destroy(gameObject);
            }
        }
    }
    
    if (damagePlayer && other.CompareTag("Player"))
    {
        PlayerHealthController playerHealthController = other.GetComponent<PlayerHealthController>();
        if (playerHealthController != null)
        {
            playerHealthController.DamagePlayer(RandomDamage());
            StartCoroutine(playerHealthController.FlashDamagePanel());
        }
    }

    if (other.CompareTag("AR Floor"))
    {
        Destroy(gameObject);
        Logger.Instance.LogWarning($"Hit {other.name}");
    }
}

[hexed pecan]

The script component with OnTriggerEnter should be on the object that has the rigidbody

[tawny mountain]

it is

the bullet object

[hexed pecan]

Might wanna show the bullet object then

[hexed pecan]

Also how do you move the bullet? 🤔

[tawny mountain]

I did put a log in the top of OnTriggerEnter and it is getting called ,

[hexed pecan]

Are you saying that the other collisions are working, just not Enemy and Head?

[tawny mountain]

Correct

[tawny mountain]

I was using Enemy tag on parent , when i changed it do head shots , i moved the tags to the child{0} and child{1} objects and they dont work

[hexed pecan]

Are you sure that the parent doesn't have a rigidbody

[tawny mountain]

Positive

[hexed pecan]

@tawny mountain This is relevant

And make sure that damageEnemy is true when you want it to be

[tawny mountain]

It always true for this projectile , it the players projectile

[eternal kestrel]

i ficed the overlap issue with the panels but turns out it wasnt really an overlap issue

is there a way to set an object inactive when another one is active?

[tired stump]

hello

i have a issue regarding unity

[spring creek]

https://dontasktoask.com/

Oh... that was the info needed. Why delete?

[eternal kestrel]

this is the code im using for the finishline

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class FinishLine : MonoBehaviour
{
    public GameObject winPanel;
    public GameObject losePanel;


    private void OnTriggerEnter(Collider Col)
    {
        if (Col.gameObject.tag == "RealPlayer")
        {
            winPanel.SetActive(true);

        }

        if (Col.gameObject.tag == "Player")
        {
            losePanel.SetActive(true);

        }
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

[tired stump]

i thought i was wrong

it tells me my script has erros/doesnt work but no errors can be present

from what i found

[spring creek]

And do you have compiler errors? (In unity, not the ide)

[tired stump]

no? i dont think so

[spring creek]

Ok, show a screenshot of the whole ide please. (Uncropped)

Of playermovement

[tired stump]

ide as in script?

[spring creek]

Integrated Development Environment.

Looks like you are using VisualStudio

[spring creek]

This is called Simplemovement while the file is called playermovement

So that may be the issue

Your file must match the class name in most unity versions

[simple egret]

You actually have two scripts here, seeing the tabs, maybe you swapped out their contents?

[spring creek]

That's what I was thinking too

[tired stump]

this was a deleted script

i just forgot to remove it

[spring creek]

So... in Unity rename the file to the same as the class. And redrag it into the box

[hard viper]

in general, you want to be careful deleting/renaming scripts outside of unity

[simple egret]

class Test goes in a file named Test.cs, for example.
Try to follow the standard naming conventions for C# types: "PascalCase". Capitalize the first letter of each word: SimpleMovement

[hard viper]

if you delete/rename a file within unity’s editor, it’s pretty smart at realizing what files connect

not so smart if you do it elsewhere

and others are right where you want filename to match class name

[tired stump]

how do i rename the file?

[spring creek]

Right click the file in the Project window in unity. Select rename

[hard viper]

because if I make a file called Movement.cs, and it has PlayerMovement : Monobehaviour, and EnemyMovement: Monobehaviour, when you drag the file, Unity will not be able to tell which class is supposed to be on the gameobject

[tired stump]

[hard viper]

but I CAN make PlayerMovment.cs, with PlayerMovement : Monobehaviour, and define several other classes in that file. And all is ok

[tired stump]

wait is this the issue

[spring creek]

And then redrag the script into that box, as I said

[tired stump]

the missing upper case M

[spring creek]

Yes

It must match EXACTLY

[hard viper]

those are two totally different names

[tired stump]

ah ok

[spring creek]

Rename the class for this. As it should be PascalCase

But it's up to you. Just a normal style preference

[hard viper]

it should be

PascalCase is correct general notation for classes

[tired stump]

let me scan through and see any other misswording

[hard viper]

remove the component entirely, and add it fresh

[tired stump]

i readded it and it still gives me errors?

[heady iris]

This will happen if you move or rename a file outside of Unity or your code editor. Unity thinks that the old script asset was deleted and that you created a new one.

[hard viper]

that is working

[tired stump]

so the issue is within the script itself?

[heady iris]

That's something wrong on Unity's end.

I would just restart the editor if it's persisting.

[tired stump]

the program?

[hard viper]

yeah. unity had a stroke

[heady iris]

Yes. The Unity editor.

[hard viper]

restart it

[tired stump]

so i need to be really careful with how i word things

[heady iris]

computers do not try to creatively interpret what you write

[tired stump]

ayy

[spring creek]

More people should have teachers that do the "i'm a compiler, tell me how to make a peanut butter and jelly sandwich"

It was fun and really eye opening in like second grade when we did it.

"Get bread", ok grabs whole loaf

[tired stump]

nevermind

[heady iris]

These are different errors.

And , this time, they're your code's problem.

The first exception happened because the variable named rb was not assigned.

[spring creek]

Runtime errors it looks like

[heady iris]

The second exception happened because there is no input axis named "horizontal"

again: computers are very literal

it doesn't matter that there is an input axis called "Horizontal"

"horizontal" is not "Horizontal"

[tired stump]

this rb?

[heady iris]

Correct.

[spring creek]

Yep. You have a DECLARATION there. You now need to assign it

[heady iris]

rb can hold a Rigidbody2D

This does not mean it has a reference.

You must assign one.

[tired stump]

what do i assing to it

[leaden ice]

The rigidbody you want to use

[spring creek]

I assume you want the rigidbody on the player..

[leaden ice]

from your screenshot above it looks like the one on the same object as this script is probably what you want

[somber nacelle]

the name of your gameobject has nothing to do with your code

[tired stump]

i think i got it

ignore me

ok it no longer gives me errors when i play

but i fall through the ground

[somber nacelle]

does the ground have a collider

[tired stump]

it moves

[misty blade]

is there a way to highlight a button class? There is a method Select(), but is there some tricky way to highlight it?

[spring creek]

But does it have a collider?

[rigid island]

the best way would be making your own button and use functions such as IPointerEnter etc.
this way you have a custom highlight method, I suppose even without mouse being on it

[fringe ridge]

its a long shot, but maybe someone ran into the same issue before? I'm using socketio in unity and in editor it works perfectly, but on android build it just doesnt. Nothing happens, no errors, warnings or any info (adb logcat) - just nothing happens

[chrome trail]

Would I be correct in assuming that situations like this are caused by two colliders getting snagged on each other? And, if so, how would I go about making sure they don't get snagged?

[lean sail]

is your character not able to move out?

how would I go about making sure they don't get snagged
that depends on how you are moving the player and checking for collisions in the first place

[chrome trail]

The movement takes the direction the player is moving and just applies a rigidbody force in that direction

However, when I supply input for it to turn AWAY from the block it's doing this

The only reason I can think of that a situation like this is happening is that the player's collider is getting snagged on another collider

[lean sail]

since you are using physics, the colliders wont get stuck in each other in such a way. Can you show your code

[chrome trail]

Alright

        Vector2 inputVector = input.Movement();

        //Calculate magnitude 
        float magnitude = moveForce * Mathf.Clamp(inputVector.magnitude, 0, input.LockOn() == ButtonState.PRESSED ? 0.5f : 1);

    //Calculate target angle
        float targetAngle = Mathf.Atan2(moveVector.x, moveVector.y) * Mathf.Rad2Deg + cameraAngle;
        rb.angularVelocity = Vector3.up * (Mathf.DeltaAngle(transform.eulerAngles.y, targetAngle) / Time.fixedDeltaTime) * Mathf.Deg2Rad;

        //Get a movement vector
        float moveAngle = transform.eulerAngles.y + (input.LockOn() == ButtonState.PRESSED ? Mathf.Atan2(inputVector.x, inputVector.y) * Mathf.Rad2Deg : 0);
        Vector3 movementVector = new Vector3(Mathf.Sin(Mathf.Deg2Rad * moveAngle), 0, Mathf.Cos(Mathf.Deg2Rad * moveAngle));

        //Project on a surface
        if (Physics.Raycast(transform.position + cc.center, Vector3.down, cc.height / 2 + cc.radius + 0.01f, groundingMask) &&
            Vector3.Angle(Vector3.up, groundHit.normal) < slopeLimit)
        {
            movementVector = Vector3.ProjectOnPlane(movementVector, groundHit.normal).normalized;
        }
        else if (Physics.Raycast(transform.position + cc.center, Vector3.down, cc.height / 2 + cc.radius + 0.01f, groundingMask))
        {
            movementVector = Vector3.ProjectOnPlane(Vector3.down, groundHit.normal).normalized;
        }

        //Set velocity
        rb.velocity = movementVector * magnitude + Vector3.up * rb.velocity.y;```

It's not an exact 1 to 1, but this is the relevant code

[thick socket]

not necessarily

[thick socket]

show the rigidbodies on each collider

[chrome trail]

That's just it. They don't necessarily look like they're even touching

I think I have an idea of what's going wrong, though

I think it has to do with the fact that the angle technically doesn't update instantly

So the actual movement part of the code isn't working properly

[thick socket]

wasn't sure if your rigidbody just wasn't set correctly and so you "glitched" inside of the collider

so half stuck on one side and half stuck the other

setting collision detection from discrete->continous would fix that instance (I think you have interpolate also on but not 100% about that)

[chrome trail]

And what I would need to do is use its angular velocity to "predict" where it's going to be facing by the time of the next fixed update for a proper velocity vector

[lean sail]

this isnt using rigidbody force like you described, its directly setting velocity. I would use Debug.DrawRay to see what the result of movementVector * magnitude + Vector3.up * rb.velocity.y is visually just to make sure that the direction lines up with what you think.
Theres a lot of things that you might be able to simplify here, like do you really need angular velocity on the player? If the player is a capsule then rotating it directly wont allow it to get caught on anything. The only thing angular velocity would do is allow other physics objects to get moved when you rotate against it which is a pretty niche case. If its a part of your game mechanic then well i guess keep it.
As for calculating the movement vector, theres a ton of trig going in here when you can just rotate a vector by a quaterion.
You might wanna cache that raycast as well before the if statements, no point doing it twice for the same check

[misty blade]

thanks, figured it out eventually

            GetComponent<CharacterController>().Move((MoveVector.z*transform.forward+MoveVector.x*transform.right)*MovementForce*Time.deltaTime); //irrelevant

            if(TouchCamera)
            {
                if(LateCameraMovement)
                {
                    SmoothCameraValues = Quaternion.SlerpUnclamped(Quaternion.Euler(MouseLookEuler.x, MouseLookEuler.y, MouseLookEuler.z), Quaternion.Euler(Camera.main.transform.eulerAngles.x, transform.localEulerAngles.y, 0), CameraDelay*Time.deltaTime); // somehow MouseLookEuler.z not going back to 0, even if swapping between mouselookeuler.z and 0 from the ()s
                    Camera.main.transform.localEulerAngles = new Vector3(SmoothCameraValues.eulerAngles.x, 0, SmoothCameraValues.eulerAngles.z);
                    transform.localEulerAngles = new Vector3(0, SmoothCameraValues.eulerAngles.y, 0);
                    MouseLookEuler.z = SmoothCameraValues.eulerAngles.z; //it should have been working
                }
            }

hello. i have a rigged model GO (with no components, freshly instantiated), and an animation clip array. what is the simplest way to make that model play the animations in the array at runtime?

[sharp skiff]

Been messing with some stuff and came across an interesting issue where my trajectory line is not taking into account the balls size. If the ball was the size of the line this would not be an issue but since the ball is thicker than the line with smaller angles the ball will collide earlier than the lines reflect point. Also I can think of other scenarios where this could be an issue as well ( line passing by another ball without colliding with it at a closer distance than the actual ball). Basically I am trying to go for a pool ball table type aiming trajectory line. I'm surprised I cant find much online about this. I have attached a gif showing what I mean. I'm not even sure if its possible to take into account the balls size. Just thinking out loud but something like add collision X amount of units from the render line or use a circle collider the size of the ball at the collision reflect point to get the reflection. Or something along those lines.

I did try changing the code to the best of my understanding (which is limited for sure) to use 2D.CircleCast but I think maybe it needs more tweaking cause the results are kind of funky but I will keep at it. I have attached the code in case anyone sees something that I may not be doing correctly or has suggestions to change. Thank you.

To be honest, you should use https://docs.unity3d.com/Manual/physics-multi-scene.html

Anyone know the trick to detect collision with child objects?

[soft hare]

yo i have a collider in this 3 d game and it get turned on during animation and i have a code saying if acollison happens on this other object it get deleted but when i play the animation to swing the hammer down the object thats supposed to be deleted because of the contact does not get deleted what do i do?

[spring creek]

If the parent has a rigidbody, then the child colliders will a script with OnCollision/OnTrigger on the parent

[tawny mountain]

children object don't have a script , the colliding object has the OnTriggerEnter lodgic

[spring creek]

So what is the issue? I never said the child objects would have a script. I said the parent would

And there are two colliding objects, so which one? The parent or the one without children?

[tawny mountain]

@spring creek this is the problem , the OnTriggerEnter method in the 3rd image isn't triggering by tag , If I put a log in the OnTriggerEnter outside of the if checks it does get triggered , just seems like it can't tell the cild object tags or something

My conversation is surrounding that link i replied to above

I have a gameobject with a rigidbody and the ability to jump and I'm trying to find the apex of the jump (relative to the starting position), and to do so I use this code

//math to find the apex of the jump
-Mathf.Pow(jumpForce, 2)) / (2 * Physics2D.gravity.y * rb2d.gravityScale
//code for the jump
private void Jump() => rb2d.velocity = new Vector2(rb2d.velocity.x, jumpForce);

which is just simply (-v^2)/(2g) = d, but results in a far greater predicted max height than the object is actually capable of

Here is the rigidbody component

[steady moat]

Your code doesnt compile...

[calm talon]

it's a snippet

[steady moat]

Yeah, but you have mistaken in your snippet

Which make it impossible to know if you made an error

[spring creek]

Oh ok. The first message I saw (the one I responded to) wasn't a response to anything, so I dunno which link you mean.

And yeah, it won't tell the tags of the children. Only the object with the rigidbody.
You can check for a script on the children and do it that way, but tags just won't work in this use case

[calm talon]

sub 30 for jumpForce, 1 for gravityscale and -9.81 for the y component of gravity

[tawny mountain]

I've done it somehow , From a Udemy tutorial I paid for by gamesPlusJames .. I'll go look at it Thank you tho

[spring creek]

You probably iterated the children and checked the tags? Like I said, it will only use the rigidbody objects tag. The rigidbody treats all child colliders as its own compound collider

You can always get references to the children. Just not from parameter object itself

[steady moat]

Given that you have correctly put the parentheses at the end, the formula seem to be correct.

[calm talon]

which results in a value of ~45.9 units, however when I actually have my gameobject jump, it has an apex of ~7 units from its starting height

[lean sail]

you should just show the full line, i believe you have more calculations going on because you have a 2nd bracket here
-Mathf.Pow(jumpForce, 2))

meaning that the division is done later than it should be

[calm talon]

maxJump.transform.localPosition = new Vector3(0, (-Mathf.Pow(jumpForce, 2)) / (2 * Physics2D.gravity.y * rb2d.gravityScale), 0);

the extra bracket is just some paranoia

[steady moat]

You could try:

• Try to do the simulation yourself without rigidbody.
• Track the position and plot it
• Find the deltaTime and see if it correspond to what it is suppose to be

[lean sail]

hm actually with 30 as your jump force, ~45 is the correct value

[calm talon]

but the object falls long before it reaches an apex of 45, which is why I'm here

[steady moat]

I can assure you that Unity does respect physics accuratly enough

So, you probably have other factor that we cannot see.

[lean sail]

if you run the test on a completely new object with nothing else in the way, it should reach 45

[calm talon]

same thing happened

apogee at ~7 units

[lean sail]

can you show more of the setup then? this should be a test in a new scene

[calm talon]

void Start()
{
  Rigidbody2D rb2d = GetComponent<Rigidbody2D>();
  print(transform.position.y);
  rb2d.velocity = new Vector3(0, 30);
}

[tawny mountain]

also @hexed pecan
I fixed it , I forgot to change the GetComponent to GetComponentInParent ... Duh me

[calm talon]

so that does work in an entirely new scene

(well, work as expected)

apparently my object experiences an acceleration of ~60

[soft hare]

wsp guys , why does this code not work? its giving me an error cannot convert double to float when all my variable are floats https://hastebin.com/share/aturofisuq.cpp

[vagrant blade]

Your variables are doubles, not floats. A float needs to have an f after it.

[soft hare]

thank you sorry i am tierd its 3 am still codin

oh also how cani hard cap it so you cannot go past a certain amount of damage do i use an if statment ?

[spring creek]

Use clamp

https://docs.unity3d.com/ScriptReference/Mathf.Clamp.html

What is going on here

if(Script.Difficulty == 1)
{
    HealthManger.health -= Time.deltaTime * 1.5 * Script.Difficulty;
}

If the difficulty is 1, then you're multiplying it by 1.

Also, why use Time.deltaTime (a small value, often around .02, but changes every frame) for health damage in OnCollisionEnter? It happens only once..

[soft hare]

oh yea sorry i exxcludeed a part of the code dificulty is divide by.01

[soft hare]

also sorry i am teird noticed it before you said it i changed it to time.tim

[spring creek]

DIVIDED by .01? That would make it bigger

[spring creek]

What? How is that better lol

[soft hare]

ye thats the point dont worry i am hard capping it at 50 damage

[spring creek]

Ok

The cap definitely makes sense there

[soft hare]

so the player wouldnt take more than 50 but at the start health would progresivly loose more

sofor the hard cap for dificulty easy the cap of damage is 50 for medium its 60 for hard is 65 for impssible its 70

Hi, this is the programming channel. Maybe try moving (deleting here and reposting) your message to #💻┃unity-talk or #🌐┃web

[frigid falcon]

thank you!

[forest prism]

So I have abilities in my game that I'm loading from Json. These abilities can be learned through different means but one of them is to have them in spellbooks you can find around the game. Is the best way to handle this by loading json into a dictionary that holds the abilityData as a scriptable object then when the item drops I connect the SO w/ the created object?

[swift falcon]

How do I reset the PrefabState scene?

So if I make changes in there and I want to reset it basically, if I try using "PrefabStageUtility.OpenPrefab(AssetDatabase.GetAssetPath(prefab));" again, it doesn't remove the unsaved changes

[toxic fern]

Because of _moveDirection.y = 0f; of the current OnMove(), the landing will be disconnected if there is an input when jumping. But I can't get rid of that code. Is there a way to solve it separately?

[spring creek]

Why can't you get rid of it? Why not set it to the current y velocity?

[toxic fern]

Because if I remove that code, the player will fly into the sky along the direction of the camera..

[spring creek]

And the second question?

But you could get rid of that and just build a vector in the if instead of using moveDirection directly

[bleak hatch]

Hi, I'm new to unity

Im currently doing a fps movement practice project

I'm wondering why many tutorials create parent item and many sub items for camera and player?

Some of them are empty and just overlaps each other, they seem to share transforms and rotation

[toxic fern]

Actually, I just found the answer to that. I realized that when I change the _rigidbody.velocity, I can use the current y value.

[bleak hatch]

what is the advantage of having these sub items?

[spring creek]

Yeah, that was my suggestion...

[toxic fern]

Thank you so much..!!

[sage latch]

How can I stop my camera from zooming (with the scroll wheel and new input system) while scrolling over a UI element?

[soft shard]

This may be a preference, there are many ways to build characters or any object in Unity, though using the hierarchy is a common one - if you have a parent object for example that holds a child camera, then you can move the entire player by moving the parent, and rotate the camera independently of the player - I use a similar setup where the parent is used to host the scripts that describe what that player can do, and their physics, while holding a child camera, and empty transforms that are later populated with different animation rigs, models, and features like weapons, etc - but this setup makes sense for the game im building cause I expect the player to swap characters during gameplay and want physics on the parent to affect how everything about the player moves, while having independent animations and camera affects - but in some setups, not everything needs to be attached to a GameObject, so having child objects might not make sense in more specific cases

[soft shard]

If this is an element thats always visible, you may have to detect mouse events for it, if its a canvas or element you toggle on (for example a "pause menu"), you could make your zoom a part of an Action Map so you can toggle it, or setup a condition to ignore the scrollwheel if your zoom works by checking in Update, or maybe toggle it with a global event when your menu becomes (in)/visible

[thick terrace]

EventSystem.IsPointerOverGameObject is a quick way to do this

[sage latch]

I fixed it, EventSystem.IsPointerOverGameObject didn't work since I have an invisible image below my UI for detecting outside clicks. What I did was just check if that object was hovered when applying mouse wheel input

[vague tundra]

Hello friends.
How can I start coroutine A and have it at some point start coroutine B and wait for B to complete its executing before continuing? Also, B should return a value for A to use.

[cosmic rain]

Aside from returning values(which is not possible with coroutines), it's pretty easy. Just yield to coroutine B from A.

I don't know if a ref/out parameter is possible. If it is you can use it to return a value I guess.🤔

[vague tundra]

Excellent, cheers!

[thick terrace]

ref/out don't work with async or coroutine methods! there's a few ways to do it but an easy one is to make a completion callback like this: IEnumerator MyCoroutine(Action<MyValue> onComplete)

[cosmic rain]

They want to have a value in the calling coroutine though.
If ref/out don't work, I'd rather pass a container object to hold the value.

Although, I'd rather just use async or something. If you need a coroutine to return a value, there's something wrong.

[thick terrace]

that's what i mean, a callback lets you pass a value back to the caller, javascript-style

[lilac scaffold]

hey people im looking for some guidance i want to make a fnaf fan game and im losing my mind i want to clamp the x rotation idk if i should be using cinemachine and their clamp functions. I want to be able to set it up so further i go it goes faster to that side of the screen what is the best way to do this its making me get really confused

[rigid island]

what is it you need exactly , this isn't very specfic

[lilac scaffold]

i want to make a office movement system like the original fnaf games

[rigid island]

what that even mean?

i never played fnaf sorry

[lilac scaffold]

exactly what i said

okay thats fair give me a minute

https://youtu.be/QXKLr6S7BOs?t=326

the best way i can explain it i know originally it was done in clickteam using a 2d image

[rigid island]

so its just a clamped security cam or w/e

[rigid island]

what do you have so far, and which part isn't working?

[lilac scaffold]

i dont even really know where to start ive had ideas but my brain is getting very overwhelmed with it rn which is why im asking for help

[rigid island]

when that happens you start smaller, breaking down big problem into smaller manageable problems

[lilac scaffold]

yeah litterally what im asking is as simple as it can be

[rigid island]

so start with the camera thing. Clamping the Y should be fairly simple

[lilac scaffold]

Thats litterally what im asking for help for

[rigid island]

well havent really presented what You tried/have tho, not much we can go on here.

[lilac scaffold]

if i knew how to do it i wouldnt be asking for help

[rigid island]

plenty of examples
https://www.google.com/search?channel=fenc&q=clamping+y+rotation+unity

aint it funny the first result is also someone making a fnaf game?
https://forum.unity.com/threads/clamping-y-rotation.1366650/

[lilac scaffold]

clamping isnt the issue its the how sould i make the camera rotate theres many ways i could do it, when im hovering over a button it moves, when i hover over trigger it moves. so thats what i need help with i need the fastest and easiest way to do it

[rigid island]

perhaps you should explain that earlier...

[lilac scaffold]

sort of hard to explain when i didnt have the words to explain it

[rigid island]

your questions aren't clear its diffcult to help

[lilac scaffold]

i litterally asked the most basic thing i could explain "how can i recreate a similar office movement to fnaf"

i know i have to use clamping but my problem is actually moving the camera

Theres many ways i could do it in my head but i dont actually know how to do them

[rigid island]

you move it with the mouse idk what else "h ow to move the camera means"

and to be honest im not here to play 20 questions

when you got real coding questions holla

[lilac scaffold]

I cant explain it any simpler. I need to have some way of changing the rotation when the mouse is at either side of the screen idk how to do it

That is litterally what ive been asking

im unsure whether to do it by trigger boxes just decrementing / incrementing the rotation while clamped or if theres another way to do it

[rigid island]

the sensible thing would be increasing /decreasing a value while moving the mouse, and that will rotate the cam in that direction

[dusk apex]

Seems like a design question rather than a coding question

[lilac scaffold]

not really as im asking how to code the thing

[dusk apex]

Oh, I thought you were asking for what was best to do given a feature you were wanting.

[lilac scaffold]

no im trying to code it so its a bit more performant and just getting my knowledge of coding practice up a bit more im technically a beginnerwith doing something like this

[rigid island]

if you're a beginner more performant is not something you should ever have to worry about

just do what works and is easiest to do

optamizations come later, and nothing here would really need be "more perfomant" aside the usuals (don't get components in update) etc.

[lilac scaffold]

so would a trigger box with on mouse enter event be the best way to do it

[rigid island]

to do what interactions?

[lilac scaffold]

because the way the original games work is if u move to the left a bit then it will slowly go left but if u put mouse all way to left it will go a bit faster and same with the right side

thats how the original game works

but also i will have to use raycasts and collision boxes to active things like lights and for the cameras

[candid gazelle]

Anyone got 3rd person camera movement script I could yoink👀 ?

[broken isle]

i made a script that is supposed to save the game on scene change. I have made an emplty game object and attached the script. but when i reload the game after a scene change everything is set back to 0 and i cant find out why.
here is my code for the GameManage script:https://hastebin.com/share/gokuyagibo.csharp

[rigid island]

that has more to do with value increasing more as you move mouse faster.. something the GetAxis deals with

[rigid island]

google has them

dont ask scripts here

[soft shard]

Unity has a free 3rd person package, unless you have a specific question about building your own

[candid gazelle]

I need something simple so I could also understand it and these people not explaining it on the internet

[rigid island]

lol what an overly complicated way to save

also stick to file not playerprefs

[lean sail]

You should use another format like json or binary, this current solution wont be scalable and will break rather easily.
Also i dont see where you call the load function. Add debugs to see if it runs/what the array contains

[lean sail]

If you feel the people on youtube arent explaining, you 200% wont understand another existing solution to be able to modify it

[lilac scaffold]

isnt json relativley bad to use because its easily editable i mean i guess your could encrypt

[candid gazelle]

You got any simple good tutorial suggestion?

[soft shard]

Forming specific questions can help with understanding, if theres something about a particular implementation you dont understand, try to search that specific thing up, and if that doesnt work, try to form a specific question about it to get pointed in the right direction

[rigid island]

nothing to do with json

and no its not bad at all

[lean sail]

U know people mod games like within the same week they come out right?

[lilac scaffold]

never said they didnt

[hard viper]

Is there a way to find if something is making Unity compile really slowly? lately, it's been pretty bad for me

[lean sail]

So then worrying about editing json isn't a real issue, if someone wants to mess with their own singleplayer experience, let them

[lilac scaffold]

i just have heard from multiple people its generally bad to use json for saving stuff

[lean sail]

You've been told wrong unfortunately then

[lilac scaffold]

but im guessing thats more multiplayer stuff

[night storm]

they should have also said a reason when making such claims

[hard viper]

if someone wants to edit their savefile, and they know enough to each your Json file, and actually edit it, they are going to edit their savefile regardless

[spring creek]

MP should be server based/validated... json would be irrelevant with that

[lilac scaffold]

idk would havethought people with multiple degress and decades in the industry wouldnt be wrong

[lean sail]

Anyone can be wrong

[spring creek]

They were 🤷‍♂️

[main shuttle]

Not really afaik, are you using assembly definitions already for your code?

[hard viper]

not really

[night storm]

did they just say "json = bad. i will not elaborate further" or did they also say a reason

[hard viper]

but idk if adding in some packages made it slow down

[lean sail]

I mean sure, you get the tiniest amount more security using binary over json... but who cares. Some guy is gonna open up your game and insert Thomas the tank engine if he wants to within the same day.

[rancid coral]

Very beginner question here but, how do I change the speed of my animation as the sample button does not seem to exist in my animator window?

[main shuttle]

Well if you don't everything goes into the same assembly definition, and everything gets recompiled with every change.
That would indeed cause it to recompile very slow in a large project.

[rigid island]

eh they're new. no worry so much

[rigid island]

dont crosspost

[rancid coral]

Sorry just need a answer because I see other people have it and wonder if it is a version thing or just a removed feature

[rigid island]

doesn't mean you're entitled to crosspost, you already asked in #💻┃code-beginner . be patient.
If no one answers it probably means you havent explained the problem clear

[lilac scaffold]

they just said its better to have information secure rather than easily editable and json is very easy to edit. Idk if they are just very anti modding of enclosed experiences tho

[rancid coral]

Is this a rules thing cuz if it is mb

[rigid island]

everything ona client pc easily editable

[spring creek]

Someone will make a tool to make editing the binary easy within a day

The only way to secure the data is to store it off the local system on a server

ANYTHING (including encryption, which would require the key shipped with the game) would be easy to edit

[rigid island]

yes #📖┃code-of-conduct

[rancid coral]

ok bro

[lilac scaffold]

tbf even if its not in the rules its pretty common sense

[lean sail]

Just to add one thing before I have to go.
This is a list of things people said is slow or bad (in comparison to something or just in general):

If statements
Reverse for loop
new input system
string.contains
unity running on 1 thread
*any* while loops in update
ints
coroutines
Json

People have misconceptions all the time. If none of these were ever good, no one would use unity or c#.

In terms of security, yes someone can open it up and edit it. But they also have to know where that file is and what to edit, chances are most people wont even care to look. They'll look online first how to do it. And the people who would tell them how to do it online would also tell them how to change it if it were binary or any other format.

[rancid coral]

I see it all the time mb for pinging more than once 😐

[lilac scaffold]

i feel like all of them its specific cases where they are bad

[rigid island]

if the game is single player it should not matter what player does with their own game

[lilac scaffold]

true

anyway another question I have is regarding getting the trigger boxes in my code. Do I make public variables and just assign them there or should i be using GetObject by name/type

[lean sail]

Some of these yea I could see cases where they are bad but that's besides the point. The if statement one was also someone claiming doing a math equation was way more efficient than checking like if(num <90 or num <180), and declared if statements as slow. This also was not a junior dev

[rigid island]

sounds like you're already jumping ahead

get the mouse look/ rotation cam working first

then move from there

[lilac scaffold]

dont i just have to enable the cursor and then when it enters the trigger rotate the Y of the camera

[rigid island]

not sure I understand why you need triggers to rotate the camera ?

[lilac scaffold]

because im mimicking how the original game did the camera rotation

https://www.youtube.com/watch?v=ujg0Y5IziiY

[rigid island]

I dont see anything about triggers

[lilac scaffold]

i think in the video it shows how the movment works

or it was another

[rigid island]

I just see a mouse rotation done the same way any RTS implements cam movement from mouse

the more mouse moves towards edge screen the faster it moves

[lilac scaffold]

i will just use paint to explain as thats the easiest visually

[rigid island]

I think you're the one misunderstanding how the mechanics are done

[lilac scaffold]

how are u so sure when u have never played the game

[rigid island]

because I can tell what I see

the mouseX axis is still being used as the rotation Y of cam

[lilac scaffold]

baring in mind the game wasnt made in unity and wasnt made by a programmer

[rigid island]

irrelevant

[steady moat]

I mean, this is a Unity server.

[lilac scaffold]

im mimicking the original

[steady moat]

So it is kinda relevant. You shouldnt ask things that are not related to Unity

[lilac scaffold]

have u even been reading or just reading like 1 or 2 messages

im mimicking the original which was made in clickteam in unity

well at least the office movement

[steady moat]

And, the answer on how to do things could, and will probably vary from an engine to an other. You better off asking support for the engine you are working with than with the engine the game has been made with.

[lilac scaffold]

so pretty much what ive been asking the entire time

[lilac scaffold]

and actually technically no as the cam only moves if its on either side in the section in the middle theres no movement

this is a botched visualization of how the original game did its movement

https://youtu.be/jAPHNtlJMkc?t=39

it was this video not the other one

[rigid island]

I get it, but those are just the hotzones doesn't mean you should use triggers lol

[lilac scaffold]

but wouldnt it be the most acurate to what im trying to achieve

[rigid island]

depends how you do it, you could just use a certain ratio away from the edges of the screen

[spring creek]

No. It would be way more work for something you can do by simply checking the mouse position

If it were VERY complex areas, maybe. But just for this, no eh, even then, I'd still just check mousePosition. Why bring physics into it?

[rigid island]

hmm luckly I'm on my break, Im gonna spin up Unity rq and try something

[steady moat]

You could use a texture and sample from it for really complex shape

[rigid island]

its really tho just a combo of Mouse position + camera clamped to certain amount @lilac scaffold

[spring creek]

Yeah, that's a good idea too

[lilac scaffold]

i might need a bit of help with the code then as im unsure how to make this happen

[steady moat]

Wouldnt that be something simular to a Deadzone/Softzone

[lilac scaffold]

thats exactly what it is and i did mention this in my original question

[rigid island]

not really but ok

lets move on

[steady moat]

If you were in Unity, you could easily do it with Cinemachine

No code involved

[rigid island]

well you still need to move the target with mousepos no?

[lilac scaffold]

all the coding i would need to do is clamp rotation right?

[steady moat]

Probably

[steady moat]

Maybe, there is multiple composer

I usually do my own camera composer

[lilac scaffold]

okay how the do i set up the zones and the mouse stuff with cinemachine

[rigid island]

its an interesting usecase for cinemachine transpose

I never done it but its worth a try i suppose

I was just thinking Mouse.position.x > or < Screen.width - edge size or w/e

[lilac scaffold]

After i get this done i got to focus on the camera system and basics of AI

[neon plank]

I noticed that Resources.FindObjectsOfTypeAll<T>() doesn't return scriptable object which weren't loaded yet... is there a method that also include them?

[somber tapir]

can't you have a serialized list where you drag & drop your SOs into?

[neon plank]

I could also drop them in the Resources folder alternatively, but I don't want to add an additional step to the tool

[lilac scaffold]

no matter how many resources i look at for scriptable objects i keep struggling to use the ones i make in game but i thik its just my inexperience

[hard viper]

You know how a POCO (plain old C class) works? Not tied to unity editor at all. just a normal class?

a scriptable object is like a POCO that lets you make files as instances

each file lets you manually edit its contents via unity inspector.

then you can just use them as inputs so gameobjects can get information out of individual scriptable objects

example:

public class EnemyData : ScriptableObject {
[field: SerializeField] public int maxHP {get; private set;}
}

public class EnemyLogic : Monobehaviour { // This component goes on an enemy
[SerializeField] private EnemyData data;
public currentHP;
private Awake() { currentHP = data.maxHP; }
}```

[hard viper]

does this help?

[lilac scaffold]

okay that does make sense its so simple yet my brain just wants to over complicate it

[hard viper]

CreateAssetMenu lets you right click in the assets panel, and there you will find a tab that says EnemySOs, and in that tab you will find Enemy Data. If you click on that, it will make a new file

that new file is a new instance of EnemyData

so I can now make a file called GoombaData.asset and KoopaData.asset

both files represent an instance of the type EnemyData

if I now edit my EnemyData class declaration, I could add a new field

public class EnemyData : ScriptableObject {
[field: SerializeField] public int maxHP {get; private set;}
[field: SerializeField] public bool turnAtLedges {get; private set;} = false;
}```

I added turnAtLedges as a bool, that defaults to false

now all the EnemyData files I already made NOW ALSO have this new field, and all of them have this value set to false

understand?

[lilac scaffold]

yeah that does make a lot more sense

[lilac scaffold]

thats pretty much what i need only question is can i speed it up a bit

[rigid island]

well yeah, i just used a very low number

[lilac scaffold]

fair enough

using cinemachine or just custom

[rigid island]

just 1 scrip, couple of lines and a cam

no cinemachine because i wouldnt know how to do this with cinemachine

[lilac scaffold]

ah nice u dont have to just give me code just give me pointers what to look at

[rigid island]

alr. I did say it earlier the logic is pretty mucheasy, the hotzones the same of any RTS edge scroll technique

instead of scrolling / panning a cam , you rotate the Y

clamp for max rotation angles

so Input.mousePosition and Screen.width are your best friends here

[hard viper]

how do I declare an extension method property?

I want to define myCollider.ForceSendLayersTrue

[lilac scaffold]

ive never really played or made RTS games

[rigid island]

I haven't myself kinda lol ut one thing I can tell you thats important from game dev is learning different mechanics you combine from diff games.
You're recycling stuff at some point, you just gotta get creative to what you're putting together

the script is dumb easy tbh.

   private void Update()
    {
        mousePos = Input.mousePosition;
        var pos = Screen.width - hotzoneSize;

       if ( mousePos.x > pos && mousePos.x < Screen.width )
        {
            rotY += rotSpeed * Time.deltaTime;
        }else if (mousePos.x > 0 && mousePos.x < 0 + hotzoneSize)
        {
            rotY -= rotSpeed * Time.deltaTime;
        }
        rotY = Mathf.Clamp(rotY, -20, 20);
        cam.transform.rotation = Quaternion.Euler(0, rotY, 0);
    }```

ofc you should not Hardcode the clamp values or any of that. this is just a quick thing I put together on my lunch break xD

its messy because of it

but it works

you can copy it but you wont learn much, but perhaps study the code and see why it works

[lilac scaffold]

Yeah i mean im more interested in what my challenges for the UI specifically for Camera system will be this movement stuff was just bugging the shit out of me

[rigid island]

this comes from lack of understanding the basics

everything feels overwhelming when we don't know

[lilac scaffold]

its why i hate unity tutorials on youtube il watch them try to understand them and still learn nothing

like sure the code works fine

[rigid island]

yeah I can make a fnaf mechanics tutorial and I havent even played the game xD

I dont know how much simpler this code itself can be explained tho lol

its pretty self explanatory

[lilac scaffold]

i mean its not the most difficult game to understand i can pseudo code it so easily but my pitfall is just unity coding knowledge

that just comes with experience , the more you use the more you know which methods are available to you

the worst thing to do is Paralysis by Analysis tho

at lot of my game designer friends esp they spent too much time doing a "thinking tank"
laying out all the mechanics on paper but 0 code
that doesn't get you very far in terms of hands on experience to what works and what doesnt

[lilac scaffold]

i also think i overthink things a lot because i dont know whats already built into unity

I am also finding visual studio a bit confusing as a code editor I really need to learn shortcuts and stuff

[rigid island]

ehh shortcuts make things a bit quicker , I have shite memory so I only know Ctrl + c + Ctrl V

so uh im not leet enough to be a shorcut daddy

[lilac scaffold]

I also have seen a lot of people have insane like code completion when im watching devlogs and stuff is that custom or paid addons

[rigid island]

thats built in the editor usually esp Visual Studio Community

or Rider

VSCode has one too but its shite atm

highly recommend the first two options

[lilac scaffold]

I technically can use rider free as im a student

[rigid island]

exactly then you should

but community is just fine

[lilac scaffold]

im guessing rider is just better than VS

[rigid island]

rider fanboys say it is

I personally use VS cause it gets the job done and i dont have to pay 100 a year

[spring creek]

V-v-vim

[rigid island]

I don't think there is any feature VSCommunity doesn't have that rider has. I could be 100% wrong on this
from my understanding jetbrains just makes them more noticable than VS

[rigid island]

if you need a config guide they have one here
!ide

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[rigid island]

this will get code completion working and list you all the unity built in methods

I’m struggling with contacts now. I still want physics system to generate contacts and collision callbacks for me

.Overlap reports overlapping colliders if .Distance says <= 0 (with float approximate zero)

Contacts seem to only be generated if Distance is actually negative

and similarly collision callbacks

[atomic sinew]

@spring creek I edited my movement script so that it only contains parts, that might be relevant to the discussion: https://hatebin.com/lqnruhysbq

i use a custom sprite animator to handle animations for the legs, those are called in FixedUpdate, see line 45 for example.

i update the collider back to its bigger size on line 9 right on the frame i become grounded

it seems, my standing animation is updated before that, thats why the player "sticks" inside the ground for a couple of frames

@misty ibex Here is my code, if you are still interested in having a look 🙂

[hard viper]

Does anyone have experience with manual simulation? I'm trying to figure out the right timing to be getting contacts and collision callbacks

[atomic sinew]

@spring creek FixedUpdate is executed before Update. I'll try moving the UpdateCollider function in there.

[abstract mesa]

Hey guys! I have a challenge that I'm facing and I'm wondering if I am going in the right direction on it.
We have an app that should be kept light weight as it'll be on mobile. We want to have certain videos or other rather heavy files that can be played at certain portions of the game. (Such as when your phone detects a certain event like you are at a certain location, a video would play for that area or something) The issue is that we need to keep things light weight so as to not have our users download multiple gigs of content that they may never need. Would Asset Streaming be the best way to go about doing something like this?

[rigid island]

like addressables and stuff

/ assetbundle

[spring creek]

Sorry, stepped out.
FixedUpdate doesn't necessarily run before (or after) update. It tries to run at a fixed time. If update takes too long, FixedUpdate will even run multiple times between updates
Because of this (attempted) regularity, it's where all physics calcluations/manipulations should be done

[atomic sinew]

I tried connecting updating the collider directly to the animations. there is still a frame of intersection, meaning, the collider is already updated, but being pushed out of the ground.

[spring creek]

I'm thinking that inside the update collider method just grab the floor and set the bottom of the collider to that? I see you are offsetting it downwards, so knowing actually where it is may help
Just like one raycast or something

[atomic sinew]

also good to know with the execution order

[atomic sinew]

hm, that sounds like a good idea

[cinder fractal]

hi im setting color to these cubes by this line of code and the cubes get shiny but theyre not supposed to and when i set the color of the cubes again it gets normal not shiny how can i stop them getting shiny?

[rigid island]

and wat is offset ?

the shine i think seems to be from emission / bloom tho

[heady iris]

You're causing bloom.

Color is allowed to go past 100% intensity when you do HDR rendering.

The bloom post-processing effect can use this to increase the amount of bloom that comes off of that object

Although, I would expect to get bloom from emission, not from just setting the base color.

Base color isn't even HDR usually.

(but maybe it's different in the built in render pipeline)

[rigid island]

oh right they might be going over the 1,1,1 limit of color and that causes emission color?

[heady iris]

Right, but albedo color is generally just in the 0-1 range

since a surface can't reflect...more light than it receives, you know

but 1) I forget how this works in the built in RP and 2) maybe this is an unlit shader

[heady iris]

If the results change when you set the color again, then you must be doing something differently

[still carbon]

If I apply the [Flags] attribute to an enum and insert such an enum into a component, Unity allows any combination of the flags to be selected, i.e. multi-select. Is there an IMGUI equivalent? I've tried EditorGUILayout.EnumPopup() but it doesn't seem to have the multi-select functionality.

[simple egret]

Google shows a hit for EnumFlagsField

[rigid island]

https://docs.unity3d.com/2017.3/Documentation/ScriptReference/EditorGUI.EnumFlagsField.html

beat me to it but yea

[still carbon]

Fantastic - thanks, guys.

[hard viper]

I figured out how to make my physics contacts to be consistent

1. Give everything +edgeradius as a skin
2. At start of custom simulation, give everything -edgeradius
3. Cast/move/etc everything around.
4. Give evertyhing +edgeradius again
5. Call .Simulate so physics system makes contacts

Hi, im trying to inherit from this class:
https://docs.unity3d.com/Packages/com.unity.postprocessing@2.0/api/UnityEngine.Rendering.PostProcessing.PostProcessEffectRenderer-1.html

but my VSC says that it cant find an import for the class, and asks:

The type or namespace name 'PostProcessEffectRenderer<>' could not be found (are you missing a using directive or an assembly reference?)CS0246

i do have an asmdef file, i downloaded the PostProcessing package (which i believe this class to be part of?) and i referenced the the Unity.PostProcessing.Runtime.asmdef which i found in the downloaded package in my own asmdef.

I dont really know what im doing with these files and references, and why, and im lost.

how do i get unity to find the package that i downloaded, so i can use it in my script?`

[somber nacelle]

try resolving the current error on line 2, then apply the changes to your asmdef again. after that see if it will recognize the namespace and class you are attempting to use

[tepid river]

resolved the script errors, but it still cant find the namespace 😦

i checked in my packages folder the file of PostProcessEffectRenderer.cs and its:
namespace UnityEngine.Rendering.PostProcessing

but i cant import that namespace.

The type or namespace name 'PostProcessing' does not exist in the namespace 'UnityEngine.Rendering' (are you missing an assembly reference?)CS0234

[rigid island]

which render pipeline are you using ?

[tepid river]

URP i think

[hard viper]

could someone clarify. In deep profiler, this says KinematicPhysics2D .FixedUpdate is being called 16 times in one frame? Is that right?

[rigid island]

might want to check

URP wouldn't use the post processing package (it has its own)

[tepid river]

well i guess that at least makes my issue obsolete lol

it is in fact URP, ill sniff into the URP post processing then, thanks 🙂

[sick flint]

I have a List<[,]> and I want to find the first available slot in the list of matrixes, how can I do this?

[tepid river]

ehm does URP not allow custom PP effects? it only states the availalbe effects in its manual, but not how to make a custom one

[wintry stone]

does anyone know how to use hinge joints im trying to make a bucket with a handle but im a little stuck can anyone help?

[somber nacelle]

https://dontasktoask.com

[tepid river]

thanks man.
this is driving me nuts, the shader itself is uber basic, but the whole boilerplate crap unity throws at me 🙄

[hard viper]

does DeepProfiler show Calls in calls/frame or per some amount of time?

I'm trying to figure out why my singletons have FixedUpdate listed as having 16 calls

[rigid island]

are you trying to make Getting Over It?

[wintry stone]

no im trying to make something similar to this post
https://forum.unity.com/threads/how-can-i-make-the-players-handheld-object-swing-around-with-the-players-movement.544796/

Im trying to set it up because of what boxfriend said so i can ask a more specific question but do you know if I need two hinge joints one for the lantern and one for the arm?

[rigid island]

depends how much movement you want really. I've done this in the past with 1 hinge joint only for the hand

[wintry stone]

oo ok im gonna set it up quickly and see if I can get it to work before asking more questions 👍

[somber nacelle]

you know kinematic rigidbodies are not affected by outside forces like gravity, right?

[limber sky]

in JsonUtility, is there a way to just write the one serializable field of that class instead of wrapping it in an object?

[wintry stone]

Yeah i just threw one onto my rb on and its working a lot better! do you know of a way that I can make the Rb move when the player flicks their mouse though?

[fallen otter]

Hey guys, i'm completely new to Unity/C#, with very little Front end development knowledge and i was wondering if i should learn C#, or at least the basics before starting to make games in unity, or if i should learn C# along the way of game development.

[somber nacelle]

depends on what exactly you mean, but you can always add force to the rigidbody if you want to make it start swinging around

[wintry stone]

I have a game mechanic where if you spin your mouse to fast it should swing it a little bit would that be possible by tracking the mouse movements and adding addForce accordingly?

[somber nacelle]

this is really all up to you and how you learn. personally i think learning c# outside of a unity context first leads to a better understanding of how the language works and how to use it in unity once you start learning the engine. but some people prefer to learn both at the same time (and there are some courses that teach that)

[somber nacelle]

yeah you could do that

[wintry stone]

thanks for the help im gonna try a couple of things the kinematic trick helped me out a lot 🙂

[rigid island]

yes

but sometimes c# alone can get a bit boring with much logic and no bells moving

balance it out, some stuff is easier to just test/play around in a quick Console application with no need for worrying GUI and stuff

[somber nacelle]

wdym the kinematic trick? i was specifically advising against making the rigidbody kinematic (that's like the whole issue with the forum post you linked). you also cannot add force on a kinematic rigidbody either

[wintry stone]

sorry i worded that poorly It helped a lot after I turned kinematic off

[somber nacelle]

ah cool

[soft hare]

Yo how do i check an objects tag that has the code attached to it

[somber nacelle]

the tag can be accessed from its gameObject

[soft hare]

how?

[somber nacelle]

do you not know how to get an object's gameObject?

[soft hare]

no i want to know how to get the tag

[somber nacelle]

christ

[somber nacelle]

and where did i tell you the tag can be accessed?

[hybrid turtle]

ok intereesting question is there a way to keep a dictionary of functions mapped to a scene. I.E. I have the following code snnippet: ``` if (Input.GetKeyDown(KeyCode.Alpha2))
{
if (_timerCoroutine != null)
StopCoroutine(_timerCoroutine);
elapsedTime = timerDuration;
}
else if (Input.GetKeyUp(KeyCode.Alpha2))
{
StartCoroutine(_timerCoroutine);
}

[soft hare]

never mind i got it
